Opening of 'Bambi' in story board (5)
I believe the answer is:
table
'board' is the definition.
('table' can be a synonym of 'board')
'opening of bambi in story' is the wordplay.
'opening of' indicates taking the first letters.
'in' is an insertion indicator.
'story' becomes 'tale' ('tale' can be a synonym of 'story').
The first letter of 'bambi' is 'b'.
'b' going into 'tale' is 'TABLE'.
(Other definitions for table that I've seen before include "Feature of restaurant" , "put forward a > schedule" , "Board; data list" , "Food; flat gem surface" , "Board < put on" .)
